RTTP.COM Organization This document specifies the "rttp" URI scheme. An "rttp" URI names a claim of intent directed at an identified subject; the address of that subject is derived by computation from the URI authority, and no lookup service, registry, or name-resolution system is consulted at resolution time. The document also states the requirements a client MUST satisfy when it handles such a URI, in order to avoid two failure modes that short, user-embeddable strings otherwise invite: using the authority as a navigation target (open redirect), and using a registered protocol handler as a general-purpose launcher.
